Hi. Good luck with everything. I'm no expect on price checks. My advice would be to go to Ebay, do a search on your item, and then click on "Completed Items" on the left hand menu. You can further filter somewhere by "Sold Items" only. Then if you sort by date, you can see the most recent transaction prices.
With that, I bet you could get $50 total delivered price with shipping for GB Jackson, opened, complete.
The nudes are much harder to compare. But in general are less than opened,complete which is of course much less than New in Box. Maybe only $10-$15 each for the nude CAMs and nude Drac/Ghoulia.
I am interested in both Gil's card and the extra locker, if they are reasonably priced. Please reply here or Private Message me.
Thanks and good luck.
